Peltier Temperature Controlled Polarimeters Comply with Latest Pharmacopeia
May 02 2018
Capable of measuring up to 3.0 OD at 589nm over a maximum tube length of 200mm, the new ADP450 polarimeter with Peltier temperature control from Xylem’s Bellingham + Stanley brand offers three decimal place precision to an accuracy of ±0.01 °Angular making it ideal for general purpose use in food, flavours, fragrance, pharmaceutical and chemical industries as well as within academia and research.
New ‘single-shot’ or continual measurement of optical rotation or other related parameter such as specific rotation and concentration is easily achieved using the instrument’s simple Methods system. Results are clearly visible on the instruments new full colour 4” high definition display and over 8000 measurements as well as a record of the instrument’s configuration may be stored, viewed and output to LIMS or Secure PDF. Calibration and configuration of the ADP450 is password protected, accessible by keypad entry or for convenience, using a fully configurable RFID tag. This, together with the audit trail, facilitates operation in environments conforming to FDA regulation 21 CFR Part 11 or GLP.
For applications where measurement is required at an alternative wavelength within the UV/Vis spectrum, the ADP600 Series of high precision polarimeters is available. Samples are applied in the Peltier temperature controlled chamber using typical standard glass polarimeter tubes for lengths 100-200mm or in leur taper low volume tubes for shorter path lengths. ADP600 Series polarimeters fully complies with the requirements of Pharmacopeia (BP/EP/USP/JP - 781) in terms of both optical rotation measurement (<±0.01 °A) and temperature control (±0.2 °C) as well as satisfying the needs of industrial researchers, who demand high precision, linear results across the whole measurement range.
